Intermediate Certificates

Due to unforeseen circumstances, No-IP has suspended issuing new TrustCor SSL Certificates. We currently have RapidSSL and GeoTrust Premium available for purchase. TrustCor SSL Certificates issued before November 11/30/2022 will remain valid until the expiration date.


The Intermediate Certificate acts as a middle-man between TrustCor and the end-user SSL.

A Root CA is a Certificate Authority (in this case, TrustCor) that owns one or more trusted roots.
That means that they have roots in the trust stores of the major browsers.

Intermediate CA is a Certificate Authority (TrustCor) that issues off an intermediate root.
They do not have roots in the browser’s trust lists, instead their intermediate roots chain back to a trusted third-party root (the root from TrustCor).

The intermediate certificates are included in the “Pem Chain” download.
